To ell whomr itmey concern:

lite it .known thatmll, FREDERICK A. Sn'rooii- LEY, citizen of theUnted States, residing at Monteur Falls in the county of Schuyler and State of leew `lt'ork, have invented der tain new and useful improvements in Con- .ciete Pipes, of which .the following is a specification.

'lhisinvention relates to sewer pipes or conduits and has for its object to provide an artificial stone pipe, the several sections of which .may be readily assembled in a trench or ditch to forni a continuous con duit of any desired length Without the ein- =ployinent of clamps, bolts, and similar' fastening devices.

rlhe object of the invention is to provide a concrete pipe section including spaced heads connected by longitddinal reinforcing rods andl provided with laterally extending` lugs for engagement with the headA of an adjacent pipe section when several of saidseo tionsnre assembled to torni a conduit, said heads not only serving to reinforce and strengthen the pipe, but also serving" to protect the ends thereof and prevent hreak age during;` transportatiini or shipment.

A further object is to so arrange 'the anchorin,-v .,l lugs of the reinforcing rods that the concrete or other material comprisingl the body of thel pipe, may he readily tanipedI during the formation of the pipe.

it. still further object of the invention is generally toii'nprove this class of devices longitudinal 4sectional view showi so as to increase their utility, durability,

and edlcieney. j' f Further objects and advantages will appear in the following' description, it being;l

`understood that various changes in forni,

Corresponding and like parts are refoi-red to inthe following description and -indicated in all the views of the drawings by the saine reference characters.

` The pipe section forming the subject niatter of the present invention comprises a concrete body portion 5 havinp,- its opposite ends provided with terminal heads ti, the latter being provided with spaced inwardly cxtendinp ears 7 having; perforations formed therein for the reception `ot the adjacent ends oflongitudinally disposed reinforcing rods 8. The opposite ends of the rods 8I are provided `with threads for engagement with suitable clamping nuts 9 and l0', which latter bear against the opper and lower faces' of the ears 7, thereby to .lock the heads in position on the rods and maintain said heads in spaced parallel relation to each other.

Embedded, in the cement, concrete, or

other plastic material 5diiring the formation of the pipe, is a strip of Woven mesh wire il, this stripof forarninons material being' interipiosod between the heads 6 and arranged to hearngrainst the' exterior of the reinfrfarcing rods d in order to assist in reintegration of the concrete.

inforcing the body portion and prevent dis- The ears T are preferably oifset so that i the upper faces thereof extend. in av plane below the plane oithe heads (i, this arrangement oi' the ears permitting' the concrete to he leveled oli' flush with the upper surface `of the heads (i and thus cover the clamping nuts 9.

Extending laterally andr` inwardly from the peripheral edge of each head 6, arey spaced lugs 1 2, preferably three in number as shown, said lugs being ada ted to receive and embrace the smooth uno structed perf tion of an adj acont-head Whenseveral of the pipe sections are assembled toform a continuous length of culvert or conduit.

"The ings 12 on one of the heads of each pipe section are arranged opposite to the lugs on the other'liead of the same pipe Section so that after one section is laid in the trench or ditch, another section maybe readily connected therewith blt/ merely forcing the smooth unobstructed portion 'i3 of an adjacentsectionwithin the lugs lflend in which Vposition the ln s .l2 of said jacent section will embrace t e smooth'unobstructed. p0rtion of the iirst mentioned section.

Attention is here celled to the fact that the heads not'only serve to reinforce and strengthen the pipe sect-ion, lout also serve in s aced relation, the innteri,

'edges of the'heads 6 being deflected down!` to house and protect the outer peri heral edge of the pipe, `therehy to prevent reaku age during transportation or shipment. It

will also he noted the?, by erranging the ears the orly of the pipe maybe readily tampa lwith e suitable tool during thel orinstio'nf of 1bhe pipe.

In constructing'the pipe section,the heads 6 are first assembled lov passing therein forcing rode d` through Athe perforar-ions therein and elemping'the loter by adjusting he nuts, 9 and l0, after which the Wire" netting 11 is interposed between 'the heads 6 and the framework thuisformedpositioned between the inner and oufer shells of a mold of any `suitable construction. The cement, concrete, or other. piestie meterlal is then shoveled or otherwise' introduced into the molding eom artmeni; between 'said shells end thorou h y tamped Toy introducing e suitable too ,between the ears 7 in the menner before stated. After the concrete is sufiiciently set the shells are assembled and the pipe sections' plseed onthe drying reeks ttoy cure.

,y it will here he noted that .hy offsetting the ears 7, the latter eetas anchoring memhers ory spurs, While the inner peripheral Wnrdly et 14e between the eers 7, serve as an additional Ineens for anchoring the heads comprising.

offenes and preventing disintegration of the cement or concrete ai; the opposite endsof the pil e.

Thusit will be seen that there is proviriiad e pipe section capable of being, oonvenientiv and expeditiously manufactured, end which may bel reedilyoonnected with or disconneeted. from'anedjecent section to permit the formation of e eondniimr culvert of any,
